STREETFLU SHER AMD GIL-DISTRIBUTER .AND SPRAYING-'MACHIITE 7'0 al] 'whomt may concern:

Be itknoivn that l, NiLs M. Rosmvoaiiii, a citizen oi the United States'of America, and resident ot livintlarop Harbor, Lake county, lllinois,have invented aeeitain new and useful Improvement in Street-Flushers and(lil lllistributers and Spraying` e Machines, oit which the followingIis a specilication.

lily invention relates to machines Yfor dis tributingg and sprayingv oilon streets, andl increase the Ageneral elliciency and desira-A bility ota street-flasher and oilfdistributer and spraying-machine of thislparticular ,character To the foregoing and other useful ends, myinvention consists in matters hereinafter set tortli and claimed.

ln the aceompanyingiv drawings- Figure l is a side elevation of astreet- 'I'lushor and oil-distributer and spraying.

machine embodying the principles of my invention.

lfig. 2 is a rear end elevation ot said machine.

in Fig. l.

Figi'. el is a detail horizontal section on line iw-4 in Figi:

Fig'. 5 is a longitudinal section on line' 5-5 in lr 2, With the forwardportion of the machine broken aivay and omitted for convenience ofillustration.

lis thus illustrated, my invention comprises a Chassis having a trame Asuitably mounted on front and rear Wheels B and C, and having an engineinelosed in a hood D at the forward end thereof, together withSpecification of Letters Patent.

Figz l" is an enlarged section on line va seat E, the general Characteroi' the Vehicle being' in the nature of an automobile truck. Suitablemeans are provided, ot course, for controlling the :trent steering"Wheels, and Jfor Controlling the engine and the transmission thereotlfrom the rear driving Wheels. v

The tank l? is preferably eylindric in character. beinev disposedhorizontally upon' the chassis .in rear ot the drivers seat. At its rearend. this tank is provided on its under side with a casting` (i forinelosingr the rotary pump lol, ivhieh latter is operated by the mainshaft 7L leading' Vto the engine. This shaft preferably supported infront and rear stntiing boxes l carried on the trout and rear closing;plates t' ot said easting'. 'The top oitthis casting,y is provided witha valveseat .l which forms the discharge-outlet trom the tank, and thevalve y' is disposed above this iat and operated by the vertieallydisposed rod I leading upivard throne-h the chamber 7i: in the rear endot the tank. and provided at its upper end with a` hand-Wheel li for theoperation et said valve. lt vvill be understood that the rod la isserien-threaded and suitably mounted rto cause it to move up and downPatented iltov. 2, i924).

when rotated by said hand-Wheel, thus open- ,ing and closing thevalve-openirui leading from the tank into said casting. i by-pass pipeleads from the bottom portion et said casting' (i upward to the dome Mon top of the tank, this' pipe beingprovided with a valve m to controlthe tion7 et the oil from the loiver discharge-opening ot the Casting;`

through the by-pass to the top ot the tank. This lower discharge-portionN ot the casting provides tivo separate outlets for the pump7 and isalso connected With a transverse pipe n provided near its opposite endswith valves and ivithv spray-nozzles@ tor spraying or distributing theoil on the snricace ot the streets. The inlet-portion l) of the casting'is also connected with a, horizontal .and laterally projecting pipe j)having a valve whereby the tank can be filled by closing the valves t)and j and opening the valves m and Q. after suitably connecting theouter end ot the pipe y? with a source ot supply. fitter the tank isfilled, the valves m and (at can then be closed. By

, opening the valves @and y', the rotation vof the pump in the castingwill draw the oil from the tank and force it downward and outwardthrough the spray-nozzles 0, ina manner that will be readilylunderstood. While the machine is standing still., and the valves 0 areclosed, the oilcan be kept in circulation andjthereby prevented fromsolidifying, especially in cold` weather, by

openingthe valve m, whereby the oil will -be drawn from the tank andvforced by the through the interior of the tank, as indi cated in dottedlines in Fig. 1, thereby to heat the oil in the tank and keep it at theThis heating appadesired temlvrlerature. ratus is, therefore, preferablydisposed at the rear end of the tank, in the manner shown, but theheating devices can be of anv suitable, known or approved character.I

' although hot water coils are found to be ef- "u of'any suitablecharacter.

fective for this purpose. burners at the rear end oiq` the tank, in themanner shown, the valve connection between the tank and the pump-housingor casting is kept hot, thereby preventing clogging between the tank andpump. Rear doors T can be provided i'or this chamber c, to form the rearend of the tank, so that the burners and heating devices will be fullyinclosed, but at Ythe same time will be readily accessible when such isnecessary. y

Pipes U lead forward between the wheels C-and have their 'rear endssuitably connested with the discharge-portion N of the casting, in frontof the pipe a, and these pipes U are provided with flushing nozzles Withthis arrangement, and after. filling the tank with water and closing allthe valves m and O and Q, the machine can then be used forl .flushingthe streets with water, the nozzles i u being provided with valves -Vsuitably connectedby rods u with the hand-levers `W suitably mounted andarranged at the side of the machine and within convenient reach of. thedriver.

lVhen hot water is employed to heat the contents of the tank, anexpansion reservoir X can be provided and suitably connected with thepipes S, so that the water, when heated, can expand in the usual andwellknown manner. v

It will also be seen that .in the passage leading from the outletopening of the tank v nozzles can be changed or varied.

By arranging the.

to the-valve' there is a strainer Y, and directly below this a clean-outopening having a plug so that access can be had to said passage to flushit with gasolene and clean it out when it becomes clogged. This strainerand the opening directly above it in the forwardly extending portion ofthe valve-connection are in front of the valve,

sothat the valve is not in the bottom opening i of the tank, but isdisposed some distance in rear thereof, thus bringing the pump out fromunder the tank.

By opening and closing the valve m in the by-pass Z, Ithe pressure oi:the oil at the In other words, this by-pass can be-.opened to someextent, by partially opening the valve m, and oil will then flow throughthe by-pass to the top of the tank, as well'as out through the nozzles,but the pressure at the nozzlesl will be less than when thev valve m isclosed. 1n this way, the valve m and the by-pass provide a means forregulating the force of the discharge without changing or varying thespeed of the pump.

llt will also be seen that the tank F is suponthe chassis. The ushing ordistributing or spraying apparatus, it will be seen, is all 'supportedby the tank, through the medium of the casting G, so that when thistankis removed the entire apparatus is taken off, so that the truck .canthen be usedr in conjunction with the hydraulic hoist Z for otherpurposes.

The fitting l which connects the pipe a with the pump has a clean-outplug 2 at the rea-r end thereof, and this tting is connected by anotheritting with vthe lower endY of the discharge-portion N of thepumphousing, this second iitting having a valve 4: which can be turnedto throw the discharge from the pump either into the pipe n or the pipe5, which latter connects with the pipes U leading to the water-nozzlesat the sidesof the machine.

It will be understood, of course, thatl a separate motive power of anydesired character can be used for operating the pump, if such is'necessary or desirable, in any suitable manner.

A seat (not shown) can be suitably mount.`

ed on the rear of the machine and in such position that the occupantthereof can easily control the adjacent valves.

lVith the 'construction shown and described, the pump easing G has twoseparate way, the connection 3 is for the single purpose ot'discharging1 the oil from the nozzles, whilethe pipe connection Z ismerely ltor the purpose of discharging,r oil froinithe pump into thetank and each connection is always employed toi' its particular orallotted purpose. ln the same way, the connection between the top of thepump and the tank is merely for the puipose of discharging oil from thetank into the pump, while the connection p is for the single purpose ofsupplying oil to the pump from a source ot supply, and neitherconnection is ever used for anything other than for its particular orallotted purpose. In this way, the cb-nstruction is simplified andclogging is less liable to occur and other practical advantages aregained as well. The top of the pump is kept hot by the heat in thecombustionchamber K, and in this way the Valve device in the top ot' thepump, and also the pump itself, are prevented from clogging and the heatof this chamber is also utilized t@ convey heat tothe interior ot thetank to heat the oil therein.
